Which exam should I take SCWCD or SCBCD or SCWSD

Which exam should I take SCWCD or SCBCD or SCWSD from potential job perspective? I'm a SCJP 6 certified and have a almost one year of experience in working with JSP-Servlets and EJB. And right now I'm working with Spring Web-Services. So learning or interest is not a big question for me as I have experience with 3 of the technologies. Please suggest me based on what recruiters ask for.
